UNITED STATES EDWARD HENRY MOLAUGHLIN, OF PARSONS, KANSAS.

ENGINEERS SEAT.

SPECIFICATION forming part of Letters Patent No. 516,314, dated March13, 1894.

Application filed May 20, 1893.

To all whom it may concern:

Be it known that I, EDWARD HENRY Mo- LAUGHLIN, a citizen of the UnitedStates, r'esiding at Parsons, in the county of Labette and State ofKansas, have invented certain new and useful Improvements in EngineersSeats; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto The accompanying drawings, and to the letters and figures ofreference marked thereon, which form a part of this specification. Myinvention relates to locomotive cabseats and has for its object theprovision of a simple, portable, inexpensive and comfortable seat forthe engineer of a locomotive which will relieve him of the side, endwiseand jolting movements of the engine.

The invention consists in certain novel features of construction andcombinations of parts of the seat or yielding platform structure, all ashereinafter described and claimed.

Reference is to be had to the accompanying drawings forming a part ofthis specification in which similar reference letters and numeralsindicate corresponding parts in all the figures.

Figure 1 is a side elevation, in partial section, of the base frame,seat and connecting parts. Fig. 2 is an end elevation in partialsection. Figs. 3 and 3 are respectively a plan and edge View of a link.Fig. 4 is a detail in elevation of one of the upper crank bars. Fig. 5is a similar View of one of the lower crank bars. Fig. 6 is a view ofone of the seat supporting springs.

Referring to the drawings, 5 represents a rectangular base frame orsupport at each of the upper inside corners of which is secured ajournal box 6 in which the bars A having the cranked portions 8 arejournaled. Links 0 provided with eyes 9 at their upper and lower endsare suspended by means of the upper eyes from the cranked portions ofthe Serial No. 474,932. (No model.)

bars A and carry in the lower eyes other crank bars B. These latter barsfor convenience in assembling the parts and for adj ustment thereof aremade in two parts the inner adjacent ends thereof being threaded toreceive a connection 13 correspondingly threaded and the said bars B arealso in their outer end portions formed with the bends 12. Secured tothe bent portions 12 through the medium of eyes 15 are the bow springs14: which springs carry the seat proper. The seat is composed of a basepiece 1,Which may be upholstered if desired, said base piece beingconnected to the springs by the bolts 22,

the heads of which are countersunk in the base board 1.

As seen by the dotted lines in Fig. 1 aweight imposed on the seat causesadeflection of the seat carrying springs and a lateral movement of thelinks 0 thus insuring an easy vertical play of the seat. Sidewise motionof the seat is allowed by the play of the upper crank bars A in theirjournal boxes and the movement of the links 0 on the bars, while endwisemotion is taken up or compensated for by the play of the links 0 on thebars A and the pivotal movement of the bars Bin the links 0.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is'

A locomotive-cab seat comprising a stationary frame bars A journaled inthe upper portion of said frame and provided with cranked portions,swinging links pivotally held in the said cranked portions of thejournaled bars, a two part adjustable bar B pivotally held in theswinging links, springs 14 connected to the bars B and a seat carried bythe springs, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
